Cryptocurrency is currently experiencing a significant surge in attention. From Elon Musk’s tweets to subtle Super Bowl advertisements and the renaming of the Los Angeles Staples Center to the Crypto.com Arena, blockchain-based digital currencies seem unstoppable—and perhaps even inevitable.
This momentum appears to be ushering us into the next phase of the internet: Web3. This new ecosystem is built on blockchain technology, crypto wallets, non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs). Yet, as we rush forward, it's essential to pause and reflect on how we arrived at this point and what these technological developments could mean for business.
To explore the origins of cryptocurrency, examine current challenges, and contextualize it within the Web3 framework, I spoke with Jeff John Roberts, a seasoned tech journalist and author of Kings of Crypto: One Startup’s Quest to Take Cryptocurrency out of Silicon Valley and onto Wall Street. He is also the executive editor at Decrypt, a leading blockchain media outlet. The following interview has been edited for clarity.
What Is Cryptocurrency?
Cryptocurrency is a broad and often loosely defined term. At its core, it refers to software that runs on a blockchain—a digital ledger that records every transaction. Blockchains are tamper-proof, decentralized, and immutable. While this might sound like a collection of buzzwords, the concept is straightforward: multiple computers run the same program to verify accuracy collectively.
Bitcoin was the first blockchain and remains the most famous. It fits all these characteristics and also functions as a payment currency. Part of what the Bitcoin blockchain records is a tamper-resistant log of transactions: who sent Bitcoin to whom.
Today, there are thousands of blockchains, each varying in quality and security. Bitcoin stands out because it was the first, has never been hacked, and demonstrated the potential of blockchain technology to the world.
The Origins and Evolution of Crypto
Cryptocurrency traces its roots to the cypherpunk movement of the 1980s. Cypherpunks were privacy-focused cryptographers and programmers based in the San Francisco Bay Area. They aimed to create a new form of currency that wouldn't rely on central banks, governments, or other intermediaries.
This goal was realized in 2008 with the publication of the Bitcoin whitepaper, which introduced a groundbreaking concept: a private, decentralized form of money resistant to hacking and independent of trusted authorities.
Indeed, the first application of blockchain technology was cryptocurrency, with Bitcoin leading the way. Its success proved that a secure, valuable digital currency was possible, paving the way for countless other applications. Think of blockchain as an operating system—creating currency is just one of its many potential uses.
The Enigmatic Creator
The inventor of Bitcoin and blockchain is known by the pseudonym Satoshi Nakamoto. In Bitcoin circles, speculating about Nakamoto’s identity is often considered impolite, but evidence suggests it was a shared identity among early Bay Area programmers. Key contributors included Hal Finney, who passed away from ALS a few years ago, and Nick Szabo, a polymath programmer and lawyer. Even if they weren’t Nakamoto, their contributions were indispensable to the project’s success.
Regulation and Control in Crypto
A common talking point among crypto enthusiasts is decentralization—no leaders, no banks, no central authority. However, all projects require some form of governance. Even Bitcoin, the most decentralized blockchain, has a core team of developers who maintain its code.
Bitcoin, like any software, requires periodic updates to improve security and functionality. While a core group oversees these updates, they don’t control the network. Other blockchains are far less decentralized, often controlled by a small group with substantial influence and funds.
The Challenge of Wealth Concentration
The term “whales” refers to individuals or entities holding large amounts of Bitcoin or other cryptocurrencies. Their significant holdings allow them to influence currency value and governance decisions.
Proponents argue that whales have a vested interest in the stability and success of cryptocurrencies. Cashing out en masse would undermine trust and devalue their assets. That said, newer, less established cryptocurrencies often experience pump-and-dump schemes, where creators hype the value before selling off their holdings.
Cryptocurrency and Web3
Cryptocurrency predates Web3, but the latter relies heavily on it. The gateway to Web3 is a crypto wallet. Popular options include MetaMask and Coinbase Wallet (distinct from a Coinbase exchange account). These wallets enable users to carry their digital currencies, forming the backbone of Web3. In contrast, Web2 only required a browser.
How Businesses Can Adapt
Companies can engage with Web3 and cryptocurrency in two primary ways. First, they can adopt cryptocurrencies as a payment method. Ethereum, Bitcoin, and dollar-pegged “stablecoins” are gaining traction for transactions. This shift is driven by a push from Wall Street retailers and financial giants like PayPal, Square (now Block), and even Apple. Cryptocurrency is poised to become a mainstream payment mechanism in the coming years.
Second, businesses must consider their role in the broader Web3 landscape. Should they set up virtual storefronts? Release NFTs? Engage with consumers in the metaverse? Luxury brands like Chanel and Gucci are already exploring these avenues, though tangible results remain limited.
Innovative Use Cases
Several companies are leveraging cryptocurrency and Web3 tools in creative ways. PayPal has simplified crypto transactions, while Coinbase continues to dominate the exchange space. These platforms are challenging traditional money transfer services like Western Union in international payments.
In the arts, NFTs are revolutionizing creative industries. Musicians like DJ 3LAU and The Chainsmokers are using NFTs to bypass traditional record labels. The gaming industry is also adopting NFTs, with companies like Ubisoft and Zynga experimenting with in-game digital assets.

Environmental Concerns
The environmental impact of cryptocurrency is one of the most misunderstood aspects of the technology. Critics often point to Bitcoin’s energy-intensive mining process, which now requires specialized servers in large warehouses.
The key question is: what energy sources are used? If mining relies on hydropower, solar, or wind energy, the environmental impact is less severe. If it depends on coal, environmental concerns are valid.
It’s also important to note that Bitcoin is just one of many cryptocurrencies. Most other blockchains don’t consume nearly as much energy. Dismissing all cryptocurrencies based on Bitcoin’s environmental impact is misguided. Additionally, traditional financial systems also consume significant energy, a point often raised by Bitcoin advocates.
The Future of Cryptocurrency
For cryptocurrency and Web3 to mature, improvements in user interfaces are crucial. Currently, accessing Web3 is cumbersome—comparable to the early internet before the invention of web browsers. Mainstream adoption will require more user-friendly tools.
Could cryptocurrency become a failed experiment? Given its decade-long evolution and continued growth, this seems unlikely. Like the internet in the 1990s, cryptocurrency’s long-term impact may far exceed current expectations.
Recent Market Volatility
The cryptocurrency market recently experienced a significant downturn. This was driven by two factors: macroeconomic forces like inflation, which depressed asset prices across the board, and the collapse of Terra, an algorithmic stablecoin, which triggered widespread selling.
Historical precedents exist for such crashes, including the 2014 Mt. Gox hack and the 2020 pandemic-induced sell-off. The market is known for its cyclicality, with periods of decline often followed by recovery and new all-time highs.
Implications for Web3
While all Web3 projects rely on cryptocurrency, a market crash is unlikely to erase blockchain technology. However, many projects will face budget constraints, and weaker initiatives propped up by speculation may disappear.
For longtime observers, this volatility confirms what they already knew: cryptocurrency is highly speculative and prone to sharp fluctuations. The main difference now is the scale—more people have lost more money. Yet, serious entrepreneurs will continue refining their products, preparing for the next cycle of growth.
